IMPROVEMENT in .VALVE-PLUGS.

I ASpecification forming part of Letters Patent No. 150,343, datedAprilQB, 1874; application filed January 2S, 1874..l

To all whom it may concern.'

- Be it known that I,` Ezm MILLER, of N ew York, in the county of NewYork and State of New York, have invented. a new and valuableImprovement in Valve-Plugs; andl I do herebydeclare that the followingis a full, clear,

vand exact description of the construction and .of a vertical sectionalview of my valve'- plug.

Figs. 2 and 3 are side elevations of the same. Figs. 4, 5, and G arehorizontal sections of the same.

l This invention has relation to a'valve or cock plug which isapplicable tomy improved Water-registering apparatus, for whichapplication for Letters Iatent of the United States was made by me onthe 3d day ofA J anuary, A.

The object of my present invention is to so construct the valve or cockplug above referred'toiliat, while it serves thepurpose of regulatingthe flow of water throughthe main pipe and registering mechanism, itwill' auto- '.niatically prevent any sudden check or variation in theforce of Water in the main frommaterially influencing the saidregistering mechanism, as will be hereinafter explained.

The following is a description of my improved valve or' cock plug: Inthe annexed drawings, A designates the main pipe, 'to which thecock-plug l?, is applied, and C C designate two branch pipes, one ofwhich, C,'leads to a .registering mechanism, (not necessary to berepresented in the drawing-Q and the other pipe, C, leads from saidmechanism back again into the pipe A. The cock-plug B is located in thepipe A between the ends of the pipes C C', and is constructed with threeports, e e162, below a valve-seat diaphragm, j', and also with two portsg g, above this diaphragm. When the two ports e e1 are fully in linewith the main pipe A, water will not ilow through the pipes which leadto and from the registering mechanism; but

` Caen B.

through the branch pipes.

by turning thecock about its 'axis more or less, any desired amount ofthe Water may be di: verted from a direct course through the main pipe,andcaused to'ow through the pipes U C. When this latter adjustmentismade the port ezfwill be more. or less exposed in line with lthe mainpipe Afand when' this port d `isadjusted fully into line with the mainpipe` all the water from the latter will be diverted Above the diaphragmf the plug B is chambcred, to receive a valve,vh., a spring, t', and anadjustable nut,

j, which latter is on a screw-threaded valve.- stein, h. The valve. h isseated on the diaprevented from turning by means of shortI Wings on it,which are received Ainto .grooves made vertically into the bore of theplug 1?.

rhe valve-stem h passes through the cap B-l ofthe plug B, @Dd through apacking suitably applied thereto, and it. has a prismatic head forreceiving a turn-key, by means of which the pressure of the spring s onthe valve h can be `nicely adjusted. Valve his applied loosely' o'n' itsstein. The objectv of the yielding valve is to prevent any suddenincrease in the dowof Water through the main pipe A from react- I1ng,*toany great degree, on the registering mechanism, for, should a suddenshoc'kgoccur in the main pipc, the valve h will rise, and allow aquantity of water to pass through the plug l5 above the diaphragm, andthence through .the ports g g, and thusmodifying the shock. v

I do not under this application claim a registering mechanism combinedwith the' im.- proved regulatingcock, as such mechanism forms thesubject of my application for a patent filed January 3, 1874, and. above.ifea

ferred to.

AWhat I claim as new, and desire .to secure by Letters `Patent, is

1. A valve-plug havinga diaphragm, f, with -yiclding relief-valve, andbelow the same both entry an-ext' povtsfo opposite YHsi 1es fand' Intstim'ony'that I 'claim ,the above I have above the sameqeziblponts.bnly, substantilly Yhereunto subscribed my name in the presenceasspeeiied. of two witnesses.
